Brace yourself

Kicker designed their CompR line of subs for people who love to hear strong bass when their music's playing. Built from the ground up with performance in mind, these subs handle plenty of power to give you the baddest bass available from the legendary Comp line.

Change this subwoofer's impedance with a flick of the built-in switch.

Overbuilt? More like built just right

Kicker's 40CWR102 10” subwoofer comes equipped with a tough, polypropylene cone that stays rigid during intense play sessions so you hear accurate bass. A custom-designed back and top plate give the woofer plenty of room to travel, while the durable rubber surround helps to control cone movement during a heavy workout. This sub uses extensive venting in its heavy steel basket to shrug off heat, so you can count on reliable performance.

Say hello to system flexibility

This Kicker CompR will handle up to 400 watts RMS so make sure you have an amplifier that'll do it justice. Its dual 2-ohm voice coils give you more wiring options when setting up your system, and this versatile sub works well in sealed or ported enclosures.

To drive this single subwoofer, we recommend a mono amplifier rated between 300 and 600 watts RMS at 4 ohms. For more information, please refer to our article on How to Match Subwoofers and Amplifiers.

What's a component sub and why would I want one?

A component sub is simply a speaker that's designed to reproduce bass once it's installed in a compatible enclosure. Think about the impact of a movie soundtrack in a big theater or even in your own home HDTV setup. A component sub can add the same kind of power to the music in your car. And a car sub is not all about the boom that you hear on a street corner (although that's cool too) - you can pair a component sub with your choice of enclosure to get bass just the way you like it, from tight and punchy to fat and loose. And once you experience music in your car with a well-tuned subwoofer, you'll never go back.

Features

Dual 2-ohm Voice Coils: This woofer features dual 2-ohm voice
coils, offering wiring flexibility. A switch on the speaker terminal allows you to
easily change from parallel (the woofer presents a 1-ohm load) to series (the woofer
presents a 4-ohm load) wiring for the voice coils.

UniPlate Construction: The woofer features a one-piece UniPlate
construction with a vented, extended pole piece and backplate. This unique design
provides the following benefits:

Optimizes heat transfer efficiency for cooler
operation

Eliminates erratic magnetic flux in the voice
coil gap

Releases pressure under the suspension for
uniform cone movement

Prevents the voice coil from bottoming out,
and the resulting damage

Tinsel Leads: CompR subwoofers use Spiralead tinsel-lead
technology; the tinsel lead wires are woven into the spider to relieve mechanical
stress.

Enclosure Compatibility

Sealed Enclosure Applications: Sealed enclosures provide the
most control over a woofer and provide accurate sonic reproduction, making them
suitable to all types of music. Kicker recommends sealed enclosures in the
following range:

Minimum Enclosure Volume: 0.8 ft³

Maximum Enclosure Volume: 3.0 ft³

Vented Box: Vented (or ported) enclosures typically provide
better overall efficiency than sealed so they are suitable for use with smaller
amplifiers, giving you more bass output from less power. Kicker recommends ported
enclosures in the following range:

Solid All the Way Around

Installed two of these under the rear seat of my 2013 Ram. Paired them with a 1000w amplifier and have them throttled down well under half way. Completely fills the cab with that perfect bass sound I was looking for. Not the kind of guy who needs to be heard coming from blocks away, but these subs will absolutely give you that if that's what you're after. Stop looking around and just go with these. Can't beat them.

Best Sub for the price

Best sub hands down for the money. I recently switched from 2-12" Rockford p3 and these two tens hit harder and clearly out perform them. Not ur typical 10" sub, these even hit those low notes that are made for 15" subs. 100% satisfied here

Hittin hard

I purchased two of these subs for my Mazda hatchback. I originally put them in a bandpass box that I had to try and save money instead of buying a new box. Even though the bass was loud it didn't sound all that great. I went ahead and spent the money on a sealed enclosure and now they sound a lot better. The subs hit hard and sound very clear and precise. My windshield wipers and mirrors all vibrate now. I hooked them up to a kicker mono amp. The subs come with a switch that allows you to select the ohm. It's made install confusing for me. When I purchased the subs The description read 2ohm subs, but the switch only allowed me to select 1ohm or 4 ohm. But after adjusting my amp wiring I was set to go. Great buy and I'm happy with them so far.

Pros:Great price, hit hard, sound great.

Cons:The ohm switch was a con for me. Had a known about it prior to purchase I would have purchased the 4ohm version that switches from 2 ohm to 8 ohm. But nothing that can't be solved by wiring your amp a certain way.
